Endemic species: Top 9 lonely animals

Sinarapan

The sinarapan is the world's smallest commercially harvested fish, and is rarely longer than half an inch. They are native to the Phillippines and found in only a few freshwater lakes and river systems. They're prized as a food source in Asia where they are fried in oil, boiled with vegetables, or dried and salted. In addition to having to dodge the fisherman's net, sinarapan are under threat from larger invasive species that find them as tasty as humans do.
